[Mp4-tech] MPEG4 encoders with ability to segment VO from the input video stream

[Paco Gomez]

Hello,
I am new to the list, thus my apologies if I ask something very obvious or
already explained.
My question is as follows. MPEG4 standard defines VO as different objects
that are encoded separately. This is easy to understand if the video
source(s) are already delivering the VO separated (as it could be the case
in a TV studio). However, in the usual case in which a unique video signal
is presented at the encoder input, the encoder itself would have to segment
the image to find the VO present in the scene. My question is:
Is there available in the market any MPEG4 encoders with the ability to
segment VO in a scene? Is this a common feature?
Thanks in advance.
